Use this Registry Workaround

Note: Please register the registry first before making any changes.

Normally, correcting a printer driver error is simply a matter of updating, installing or reinstalling the driver. If this method does not work, you can try a simple hacking of the registry.

  1. Press Windows + R. Type ‘regedit’ in the Open field, then click OK.
  2. Search for it, then click on the following registry subkey, if it exists: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\PostSPUpgrade
  3. On the Edit menu, click Delete, then click Yes to confirm that you want to delete the PostSPUpgrade registry key.
  4. Restart your PC (OR launch’net stop spooler’ followed by’net start spooler’ from a high prompt).

After that, you should not see the specified driver invalid when you try to print something under Windows 10. You should also be able to perform the printing job.
